A Study to Evaluate the Effects of Ezetimibe (MK-0653) on the Postprandial (Following a Meal) Lipoprotein Response in Participants With Primary Hypercholesterolemia (High Cholesterol) (MK-0653-072)(COMPLETED)

June 5, 2024 updated by: Organon and Co

A Randomized, Double-Blind, Placebo-Controlled, 2-Period, Crossover Study to Evaluate the Effects of Ezetimibe on the Postprandial Lipoprotein Response in Patients With Primary Hypercholesterolemia

A study to evaluate the cholesterol-lowering effects of ezetimibe in participants with primary hypercholesterolemia (high cholesterol) after eating a meal that is high in cholesterol. The primary hypothesis is that treatment with ezetimibe 10 mg/day reduces the cholesterol concentration of the chylomicron-containing Sf≥400 fraction following a cholesterol-enriched test meal.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
  • Phase 3

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Eligible patients will be otherwise healthy men and women (if not on oral contraceptives or hormone replacement therapy) 18 through 70 years of age with moderately high cholesterol.

Exclusion Criteria:

  • Individuals on other lipid-lowering therapy (medicines that lower cholesterol) including statins (within 6 weeks) and fibrates (within 8 weeks) prior to administration of the study drug.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Total Cholesterol Concentration of Chylomicron (Sf≥400) Fractions After a Cholesterol-Rich Test Meal
Time Frame: Immediately prior to consumption of the test meal (baseline) and at 2, 3, 4, and 6 hours after test meal on Day 28 of each treatment period.
On each of 2 days prior to the last day of each treatment period, participants consumed 2 large eggs in the evening. On the morning of the final day of each treatment period, fasting participants were given a site-prepared, cholesterol-enriched milkshake that provided 1114 calories of total energy (~44% of calories from fat, ~40% of calories from carbohydrate and ~17% of calories from protein) and 504 mg of cholesterol. The milkshake was consumed over a 15-minute period. Plasma samples were collected immediately prior to consumption of the test meal (baseline) and at 2, 3, 4, and 6 hours afterwards for isolation and analysis of lipoprotein fractions. The geometric mean concentration level was calculated using data obtained at all timepoints.
Immediately prior to consumption of the test meal (baseline) and at 2, 3, 4, and 6 hours after test meal on Day 28 of each treatment period.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Total Cholesterol Concentration of Chylomicron-remnant (Sf 60-400) Subfractions After a Cholesterol-Rich Test Meal
Time Frame: Immediately prior to consumption of the test meal (baseline) and at 2, 3, 4, and 6 hours after test meal on Day 28 of each treatment period.
On each of 2 days prior to the last day of each treatment period, participants consumed 2 large eggs in the evening.
